Patient involvement and shared decision-making in mental health care

There is growing interest in shared decision-making (SDM) in which the provider and patient go through each phase of the decision-making process together, share treatment preferences, and reach an agreement on treatment choice. Although a majority of the research evaluating SDM has been conducted under "physical" health conditions, patients' participation and SDM for mental health conditions has received increasing interest since the mid 1990s. SDM in mental health care can be more complex than in general health care because that several patient characteristics, health care provider, and system level factors may hinder normalization and implementation of this model into clinical practice. To date, in comparison with other health problems, there are few studies which have assessed SDM in this context. In spite of that, evidence points favorably towards the inclusion of SDM in mental health treatment decisions, given that the majority of patients with mental illness prefer to be involved in the process and wish to have information. However, more studies are needed to provide evidence about the impact of SDM on treatment compliance and health care outcomes. In this overview, the authors present the current state and the future perspectives of SDM in mental health.
